' GATE.

SPECIFICATION forming part of Letters Patent No. 597,449, dated January 18, 1898.

Application filed August 23, 1897. Serial No. 649,191. (No model.)

To all whom it may concern.-

Be it known that I, DAVID WILSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gates; and I do declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, Which form a part of this specification.

This invention relates to reciprocating and sliding gates, particularly to gates adapted for farm use, and especially to gates intended to be opened and closed, when desired, by the occupant of a vehicle Without dismounting.

The object of the invention is to secure easy and certain action of the gate in opening and closin gand cheapness of construction.

It consists in an inclined rocking track for supporting the gate, so disposed that in the initial movement of the gate either to open or close it is necessary that it he moved up the inclination until the pivotal point of the rocking track is reached and the track is tilted in the opposite direction by the Weight of the gate, and the further movement of the latter is accomplished by gravity. f

It consists in further details of construction and of arrangement of parts, as hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side elevation of a gate embodying my invention, a portion of the fence-frame also being shown, and the movement of the gate being indicated in dotted lines. Fig. 2 is an end elevation of the gate and of the supporting-frame. Fig. 8 is a sectional detail on the line 3 3 of Fig. l. Fig. a is a detail 0f the pulley-block used n v carrying the cord by which the gate is operated.

The gate .A may be of any desired form of construction. As shown, it is made with a Wrought-iron 'metal frame carrying a Wire fabric. The gate-posts are shown at B C, and the track for carrying the gate is shown at D, being pivoted at d to a post E, set back from the gate-post B, and forming, if desired,

a part of the frame of the fence. At the rearward end of the gate an arm a projects upwardand carries at its upper end a roller a', which rides upon the track D. This is in the form ofl a straight metal bar pivoted as already described and having its ends inclosed by loops l) g, fixed, respectively, to the post B and'to a post G, forming a part of the fence-frame, these loops l) g being adapted to prevent lateral movement of the trackbar and to limit its angular movement in a vertical plane.

A tailpiece A is iixed rigidly to the rear end of the gate Aand extends back therefrom, and is provided at its rearward end With a roller f, running between a pair of horizontal parallel guide-bars fixed to the post Gand to the adjacent fence-post II. A clipb', secured to the lower end of the post B, entends upward to engage the bottom of the gate, so as to prevent its lateral movement, and clips c c,

xed to the post C, receive the forward edge of the gate when it is closed.

A cord K leads from the top of the arm a through a swiveled pulley-block M, mounted at the top of the post E, the end of the cord K being attached to a cord O, which has its ends attached to a pair of posts P P, located at the side of the driveway, one upon each side of the gate, and removed therefrom a sufcient distance so that the rope is in convenient position to be grasped by the occupant of a vehicle desiring to pass through the gate. l

The gate may be Opened by pulling upon either end of the cord O, so as to draw the roller 0, up the inclined track D to the pivotal point d, the engagement of the roller f with the track F preventing the gate from oscillating about the roller 0, as a center. Then the pivot-pin d has been passed by the roller af, the track-bar D is tilted to the position shown in dotted lines in Fig. I by the Weight of the gate, and gravity causes the roller a to run down the incline and complete the movement of the gate in opening. When the gate IOO shown in solid lines in Fig. 1, and the further movement of the gate to @lose it is aeoomplished by gravity.

The movement of, the gate is rendered oomparetively easy byfreason of the fact that the entire gate :und its appurtenances need not be elevated, but thegete, is osoillated yineJ Vertical plane from they kroller f as e center. As the track-ber D is merelya straight bar of, ironit is very cheep ofk construction, and

in'praotioe it becomes unnecessary to work up speolel traek-bersfor gates of different lengths, as it is immaterial Whether or not f the ends of thetraek-ber project beyond thek s I5 loops bg, endhenoe if a, gate is somewhat shorter than the ystandurl measurement vthe postsB G are merely setsom ewhet closer tof gether I Claim es my inventionyl. The combination with a reciprocating gate, a frame for supporting the gate, and a Y horizontal guideweyxed tothe frame, of a roeking ,track-ber carried by the supportingmovemenm of a, reciprocating gate, a roller Secured to the rear end of kthe gate and runL ning on the track-ber, ail tailpieoe projecting yloaelcWardly fromfthefgate, a peir of parallel horizontal guide-bers secured tothe support-y ing-frame and e roller secured to the teilpieoe and running between, the guide-bars.

In testimony whereof I afxiny signature in presence of'two Witnesses.
